Hi Ivan,
Thank you for contacting Syncfusion Support.
We can position the picture in Background by using the
PdfGridImagePosition property. Please refer the attached code snippet.
Code Snippet:pdfGrid.Rows[0].Cells[0].Style.BackgroundImage = new PdfBitmap(imagePath);
pdfGrid.Rows[0].Cells[0].ImagePosition = PdfGridImagePosition.Center;
